The atomic mass for carbon is 12.01 amu.

The atomic mass for carbon can be calculated using the given data. The percent abundance of carbon-12 is 98.90%, and its mass number is 12.

The percent abundance of carbon-13 is 1.10%, and its mass number is 13.

Using this information, we can calculate the atomic mass using the formula:

(0.9890 x 12 amu) + (0.0110 x 13.003355 amu) = 12.01 amu

Therefore, the atomic mass for carbon is 12.01 amu.
